WARNING
•Under-inflation is the most common cause of tire failure and may result insevere tire cracking, tread separation,or "blow-out," with unexpected loss ofvehicle control and increased risk ofinjury.
• Under-inflated tires reduce the loadcarrying capacity of your vehicle.
When weather temperature changes occur, tire inflation pressures also change. A 10-degree temperature drop causes a corres-ponding drop of 1 psi (7 kPa) in inflation pres-sure. Check your tire pressures frequentlyand adjust them to the proper pressure,which can be found on the vehicle's tire infor-mation placard or certification label.

Tire inflation – checking pressure
Inflation pressure should be checked when the tires are cold.
Cold tiresThe tires are considered to be cold when they have the same temperature as thesurrounding (ambient) air. This temperature is normally reached after the vehicle has been parked for at least 3 hours. After driving a distance of approximately 1 mile (1.6 km), the tires are considered to behot. If you have to drive farther than this dis-tance to pump your tire(s), check and recordthe tire pressure first and add the appropriateair pressure when you get to the pump. If checking tire pressure when the tire is hot, never "bleed" or reduce air pressure. Thetires are hot from driving and it is normal forpressures to increase above recommendedcold pressures. A hot tire at or below recom-mended cold inflation pressure could be sig-nificantly under-inflated.
To check inflation pressure:1. Remove the cap from the valve on one
tire, then firmly press the tire gauge onto the valve.
2. Add air to reach the recommended air pressure. 3. Replace the valve cap.
CAUTION
•
After inflating the tires, always reinstall the valve cap to help avoid damage tothe valve from dirt, gravel, etc.
• Use plastic valve caps only. Metal capscould corrode and become difficult toremove.
4. Visually inspect the tires to make sure
there are no nails or other objects embedded that could puncture the tireand cause an air leak.
5. Check the sidewalls to make sure there are no gouges, cuts, bulges or otherirregularities.
6. Repeat this procedure for each tire, including the spare 3
.
NOTE
• If you overfill the tire, release air by pushing on the metal stem in the cen-ter of the valve. Then recheck thepressure with your tire gauge.
• Some spare tires (available as anaccessory) require higher inflationpressure than the other tires. Consultthe tire inflation pressure table, see

The following tire pressures are recom- mended by Volvo for your vehicle. Refer tothe tire inflation placard (see Tire inflation –general information (p. 301) for its location) for
information specific to the tires installed onyour vehicle at the factory. Some of the tire sizes listed here may not be available for all models in all markets.

WARNING
19” wheels may never be used on vehicles
that are not equipped with the R-design or
the Sport chassis options. Using 19” wheels on vehicles equipped the standard chassis presents a safety
risk and the risk of damage to the vehicle,and impairs the vehicle’s driving characte-ristics.
NOTE
Please consult a Volvo retailer’s Parts department for the most up-to-date speci-fications.

Snow tires/studded tires5
Owners who live in or regularly commute through areas with sustained periods of snowor icy driving conditions are strongly advisedto fit suitable winter tires to help retain thehighest degree of traction.
Tires for winter use:
•
It is important to install winter tires on all four wheels to help retain traction duringcornering, braking, and accelerating. Fail-ure to do so could reduce traction to anunsafe level or adversely affect handling.
• Do not mix tires of different design as thiscould also negatively affect overall tireroad grip.
• Winter tires wear more quickly on dryroads in warm weather. They should beremoved when the winter driving seasonhas ended.
• Studded tires should be run-in 300 – 600 miles (500 – 1000 km) during whichthe vehicle should be driven as smoothlyas possible to give the studs the opportu-nity to seat properly in the tires. The tiresshould have the same rotational directionthroughout their entire lifetime.
NOTE
Please consult state or provincial regula- tions restricting the use of studded wintertires before installing such tires.
Tire pressure monitoring - introduction
Volvo provides two different systems to moni- tor tire pressure: Tire Pressure MonitoringSystem (TPMS) or Tire Monitor.
Determining which tire monitoring system is in your vehicle
To see which system is installed in your vehi- cle, press the
MY CAR button on the center
console. Go to
SettingsCar settings.
• If your vehicle has a menu called
Tire
monitoring, see Tire Monitor - introduc-
tion (p. 315).
• If your vehicle has a menu called
Tire
pressure, see Tire Pressure Monitoring
System (TPMS) – general information (p. 311).
Introduction
Each tire, including the spare 6
(if provided),
should be checked monthly when cold and inflated to the inflation pressure recom-mended by the vehicle manufacturer on thevehicle placard or tire inflation pressure label.(If your vehicle has tires of a different sizethan the size indicated on the vehicle placardor tire inflation pressure label, you shoulddetermine the proper tire inflation pressure forthose tires.) As an added safety feature, your vehicle has been equipped with a tire pressure monitor-ing system that illuminates a low tire pressure telltale (
) when one or more of your tires
is significantly under-inflated. Accordingly, when the low tire pressure telltale illuminates,you should stop and check your tires as soonas possible, and inflate them to the properpressure. Driving on a significantly under-inflated tire causes the tire to overheat and can lead totire failure. Under-inflation also reduces fuelefficiency and tire tread life, and may affectthe vehicle's handling and stopping ability.Please note that a tire pressure monitoringsystem is not a substitute for proper tiremaintenance, and it is the driver's responsi-bility to maintain correct tire pressure, even ifunder-inflation has not reached the level to

Tire Pressure Monitoring System (TPMS) – changing wheels
Please keep the following in mind when changing or replacing the factory installedTPMS wheels/tires on the vehicle: •
Not all aftermarket wheels are equipped with TPMS sensors in the valves.
• If the vehicle is equipped with a tempo-rary spare tire, this tire does not have aTPMS sensor.
• If wheels without TPMS sensors aremounted on the vehicle, a text messagewill displayed in the instrument paneleach time the vehicle is driven above20 mph (30 km/h) for 10 minutes or more.
• Once TPMS sensors are properly instal-led, the warning message should notreappear. If the message is still displayed,drive the vehicle for several minutes at aspeed of 20 mph (30 km/h) or faster toerase the message.
• Volvo recommends that TPMS sensorsbe fitted on all wheels used on the vehi-cle, including winter tires. Volvo does notrecommend moving sensors back andforth between sets of wheels.
CAUTION
When inflating tires with TPMS sensors, press the pump's mouthpiece straightonto the valve to help avoid bending orotherwise damaging the valve.
CAUTION
• After inflating the tires, always reinstall the valve cap to help avoid damage tothe valve from dirt, gravel, etc.
• Use plastic valve caps only. Metalcaps could corrode and become diffi-cult to remove.
NOTE
•
If you change to tires with a different dimension than the factory-installedones, the TPMS system must bereconfigured for these tires. This mustbe done by a trained and qualifiedVolvo service technician.
• If a tire is changed, or if the TPMS sen-sor is moved to another wheel, thesensor's seal, nut, and valve coreshould be replaced.
• When installing TPMS sensors, thevehicle must be parked for at least15 minutes with the ignition off. If thevehicle is driven within 15 minutes, aTPMS error message will be displayed.
